<p>A bearing (22) for a sail furling apparatus includes a spherical body having a longitudinal axis (A) and containing a cylindrical longitudinal through-opening (24) for receiving a cable (4) of the furling apparatus. The body is freely rotatable on the cable (4) and protects the furled sail from abrasive contact with the cable (4). The body contains a plurality of spaced longitudinal grooves (30) in the outer surface to define a plurality of spaced flutes (32) to further space the furled sail from the cable (4) and to facilitate smooth furling and unfurling of the sail (2).</p> |
